Abstract

A spent catalyst made initially by reacting a halogenatable refractory oxide selected from Groups II-V of the Periodic Table with a compound of general formula <FORM:0969863/B1-B2/1> (where X and Y are the same or different and selected from H. Cl, Br, F or SCl or where X and Y may be replaced by O or S) under non-reducing conditions and at a temperature such that chlorine is taken up by the oxide without the production of free chloride and which has become deactivated during a low temperature conversion process, is regenerated by contacting it at an elevated temperature with an oxygen-containing gas and thereafter rechlorinating the catalyst with a compound of the above general formula. The halogenatable refractory oxide may be alumina with up to 50% silica, titania, beryllia, boria, zirconia or magnesia. Additionally the catalyst may contain platinum or palladium. Specified chlorinating agents are CCl4, CHCl3, CH2Cl2, CCl2F2, CCl3Br and CCl3SCl. When the halogenatable refractory oxide is Al2O3 it may be prepared by hydrolysis of aluminium isopropoxide in an inert solvent, e.g. benzene. Examples are given. Specifications 953,187 and 953,189 are referred to.
